<1 and <2 are congruent because they are a pair of vertical angles.
Answer:
b=5
Step-by-step explanation:
2+b=7
Subtract 2 from each side
2+b-2=7-2
b= 5
We assume the two numbers are x and (x+1)
so x^2+(x+1)^2=421
x^2+(x^2+2x+1)=421
2x^2+2x-420=0
According to the formula of quadratic
x=14 or-15
cuz we know the two numbers are integers
so x=14
therefore the other number is 15
To make sure that's correct
14^2+15^2=421
Hope that helps you!!
